Acacia pickardii is a bushy shrub or tree growing to 5 m high with golden globular flowerheads (Orchard & Wilson 2001).

This species is known from far north-eastern SA and south-eastern NT (Jessup 1981; Maslin 1992). The species grows in two main areas: in the Mt Gason Bore/Pandie Pandie area, 150 km south of Birdsville, SA; and the Andado Station-O'Neill Point area, NT (Whibley & Symon 1992; Maslin 1992; Davies 1995a).

In South Australia the species was locally common at Mt Gason Bore (Tindale 1978). Two populations were found in 1995 to the south of Mt Gason Bore on Koonanie Pastoral Lease, run as part of Cowarie Station. One population of 30 trees occurs on the eastern side of the Birdsville Track. The other occurs on the northern side of the Witchy Witchinna Waterhole Track (Davies 1995a).

Another two populations are known to occur adjacent to the Birdsville Track in the vicinity of Mt Gason Bore: one, containing about 250 plants, covers 30 ha of Goyder Lagoon Pastoral Lease, the second of 100+ plants on Kanawana Pastoral Lease. Both populations are part of Clifton Hills Station (Davies 1995a).

In 1993 an extensive population was located in the area north of L. Etamunbanie, east of Pandie Pandie Homestead on the Pandie Pandie Pastoral Lease. The population is north of Caves Dam on the track to Calpan Dam. Cattle browse the ground stratum. No regeneration was observed (R. Barrett 1995 pers. comm. in Davies 1995a).

A population of 50 plants has also been observed adjacent to a large cleared area previously used as a highway workers camp, south of Mt Gason (F. Badman 1993 pers. comm. in Davies 1995a), though it was not relocated in a subsequent survey (Davies 1995a).

In the NT the species occurs in the Andado Station-O'Neill Point area, 400 km north-west of Mt Gason (Orchard & Wilson 2001). It appears to be extremely rare in the NT, being known from only two small and one larger population, on the edge of the Simpson Desert. One of these is near, but outside, the Mac Clarke (Acacia peuce) Reserve. In total, there are several hundred individual plants at the three NT locations (Kerrigan et al. 2002b).

This species is most closely related to A. cuspidifolia but distinguished from this species by its pungent (sharp) cylindrical phyllodes (Orchard & Wilson 2001).

Acacia pickardii is superficially similar to A. atrox, a recently described rare species from NSW, in that it has pungent phyllodes, spreads by suckering, produces hakea fruit-like galls on its foliage and appears to rarely produce fruit, but differs most obviously in its erect, cylindrical phyllodes, and in having spiny stipules and free sepals (Kodela 2001).

This species grows on gibber-covered sandplains and in stony sand over clay on low residual mesas and adjacent flats (Orchard & Wilson 2001). Soils are crusty alkaline and neutral red duplex. Average annual rainfall is 150 mm (Whibley & Symon 1992).

The species forms a low woodland or low open woodland. The understorey varies from a dwarf open shrubland dominated by Atriplex vesicaria or Sclerolaena lanicuspis, to open grassland dominated by Aristida contorta. Less frequent understorey dominants include Malacocera tricornis, Enchylaena tomentosa and Sporobolus actinocladus (Davies 1995a).

Flowers are borne irregularly, probably after good rain (Jessop & Toelken 1986; Whibley & Symon 1992). Seed set is extremely poor; seedlings have not been observed (Kerrigan et al. 2002b). The species spreads by suckering (Davies 1995a; Orchard & Wilson 2001).

The following table lists known and perceived threats to this species. Threats are based on the International Union for Conservation of Nature and Natural Resources (IUCN) threat classification version 1.1.
